Univoq / Iconiq drip stop issues?

[PSQ]

Anyone having issues with drip stop valve rubbers failing when spraying Corteva’s Univoq, Iconiq or similar?

Seems to a bit of an issue among sprayer drivers having widespread DSV failure on FB.

Not yet. But I’m only on the third tank.

I’ve seen the same and looked in my Chen store to find some univoq been delivered for a customer yesterday. Not used it yet and not so keen to either now.

Yes, just changed all of our diaphrams and sent 1000 lt of Univoq back.

Fingers crossed I’ve been okay, done about 450ha since Sunday morning with bateman on the last load now. Horsch he has had to change 2 diaphragms but that could be coincidence. In total used over 1000l.

we have been using quite a mixture of goodies in the tank, foliar urea n20 at 25l/ha, fulvic acid, citric acid, molasses which may be helping?
As I write this last load is univoq on its own and just noticed some dripping…!

Yes have issues here. Thought it was my sprayer (horsch). Dripping from nozzles and having to mess around with rubber diaphragms.

That foliar urea any different to standard soil applied nufol for example?

It’s the same but we melt it ourselves. Essentially trying to make something to be taken in by the leaf hence the citric, fulvic etc playing with different rates on different crops to see how it works

Aicc sent this out earlier

Been told it has done 40k of damage to an agrifac sprayer. Damaged all the solenoid valves at each nozzle. Agrifac have run out of replacements

Not had any problems yet but only been using it today so will see tomorrow if I have any problems

Iv used 115 litres since Saturday and ok so far.

 

[ajd132]

I think my diaphragms on my bateman are so ancient that they could shake off lava. Finished t2 now so washed it thoroughly, will put some water in tomorrow and see if it’s okay

Topic was okay in my sprayer with it, the last 70ha had it

 

[teslacoils]

Well, I'm going to use it, but as I've only a small area I shall clean the tank out; use the univoq on its own as per the instructions above; and then go back and apply the rest later.

started on Saturday, not washed out till today. Just had teb mixed with it. New Amazone sprayer.
